| 摘 要： | 通过对地震时不同型号仪器及不同采样率获取的水位观测曲线进行对比分析,结果显示:目前我国数字化水位观测的两种主要观测仪器ADP系统与LN-3(A)在记震能力上的差别主要是由采样率不同引起的,与仪器性能及水井的深度关系不大.由于水震波的持续时间一般只有几分钟,因此只有加大采样率,才能记录到波型更为完整的水震波和更为丰富的水震波震例.分析认为,数字化水位观测必须最终向实时记录的方向发展,才能更真实准确地反映地球内部应力的瞬时变化的真实信息,不至因采样率不足而使短周期信息遗漏,同时也更有机会捕捉到前驱波及区域应力场的变化.

| Abstract: | This paper aims at the comparison of the observation at different water levels obtained from instruments of different models and sampling ratio when an earthquake occurred,the results show that:the differences of recording earthquake between the ADP system and LN-3(A),mainly used in our country at present,which are the two main observation apparatus used for Digital water level observing,are mainly caused by the differences of sampling ratio,having nothing to do with the performance of instrument and the de... |
